Can I Safely Do Cardio Exercises Now?

I am 38 years old male runner and training for marathon,, but on some days while running I lose my energy and feel dizzy and unable to continue, sudden hunger and my strength completely fades for about a quarter of an hour and then I continue. I noticed that my blood pressure drops through examination (80/40) so I did blood tests, ECG, chest x-ray, sinus x-ray and everything is good. What can be the cause, and what should I check next?

Hello, I have been having pain in my right shoulder and in my chest around my heart area, but when I take my prescribed medication for my heart. It doesn't alleviate the pain. I had a massive heart attack back in 2011 and I currently have a defibrillator, so now I take Aspirin, Lisenapril and a couple of other meds, but I notice that I still have pain on my left side which makes it kinda hard to breathe. I work as a dishwasher and I don't do a lot of heavy lifting, so I don't know what it could be. I can barely lift my arm because of it. Please help!
